Depending on the voltage necessary for the motor’s operation, you can choose a low or high voltage controller. A switching regulator works well for controllers with a wide operating voltage range.
This example will show how to model a DC motor's speed using different approaches in Collimator. The three approaches involve simulating diagrams from a differential equation, a transfer function, and a state variable model. Then, we will design and simulate a PID controller for the DC motor speed.
When power is supplied, 555 TIMER generates PWM signal with a duty ratio based on the pot resistance ratio. Because of the pot and the diode pair, here the capacitor (which triggers the output) must charge and discharge through a different set of resistance and because of this, the capacitor takes a different time to charge and discharge.
A rheostat, that is, a variable resistance is connected in parallel with the motor armature winding. Hence called shunted armature control, also called as armature diverter control.
A breadboard, electrical tape or solder to make solid connections in the circuit. A tutorial for using breadboards can be found below.
The shunt field current is relatively small, the field rheostat has to carry a very small current and hence I2R loss is so small. It is an efficient method of controlling the speed of a DC shunt motor. Using this method, speeds above the pelo-load speed can be achieved.

But here we look at just three coils, spaced at 120º. A motor, as we noted in our last session, performs the task of converting electrical energy into mechanical energy. So how does the motor in our illustration do this? Let’s look at what goes on inside.
Prepare the power supply. If using a power pack, install the batteries so the + and - sides are facing the correct directions in the housing. If it can be done, keep the power supply off for now.
In addition, we’ll share our personal experience and brief you on the design and challenges that you can meet while building your own controller.
Circuit diagram of DC motor speed control using arduino is shown in the figure below. The working principle and program of this circuit is same as that of the LED brightness control. Only difference is that and additional motor driver circuit using a transistor is included in the circuit.
Author From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and regardless of the application, controlling the speed and direction of these motors is essential to make them functional and effective.
It allows the device powered by this motor to shift and fix positions with high precision. A stepper motor controller provides current in pulses, energizing poles of the stator and making the rotor move.
For instance, a DC motor controller for an industrial brushed motor uses different working principles and has a different design compared to a controller for DC motors in electric vehicles.
